The effect of immediate dentures on maxillomandibular relations

Area of Science:

• Dentistry
• Prosthodontics
• Oral Surgery

Background:

• Immediate dentures are commonly used after tooth extraction.
• Understanding dimensional changes with immediate dentures is crucial for patient satisfaction and prosthetic success.

Purpose of the Study:

• To evaluate changes in vertical dimension of occlusion and rest position over three months with immediate dentures.
• To assess the effect of a non-interfering occlusal scheme on these dimensional changes.

Main Methods:

• Six patients received immediate mandibular and maxillary dentures.
• Cephalometric measurements were taken at baseline and at 1 week, 1, 2, and 3 months post-insertion.
• Dentures were relined after two months.

Main Results:

• The mandible showed a forward shift in centric occlusion within one week, persisting for three months.
• No significant anteroposterior change was observed in the mandibular rest position.
• A gradual decrease in the vertical dimension of occlusion and rest occurred throughout the study.
• Relining the dentures did not alter the observed dimensional change trends.

Conclusions:

• Immediate dentures can lead to forward mandibular positioning and a decrease in vertical dimensions.
• A non-interfering occlusal scheme appears beneficial for immediate denture wearers.
• Further research may explore long-term stability and patient-reported outcomes.
